VALDOSTA – A detour for Interstate 75 South traffic at Exit 13/Old Clyattville Road has been extended.

The detour was originally scheduled for Monday, Tuesday and, if needed, Wednesday. Contractor Southern Concrete Construction Co. was unable to do any work Tuesday night because of stormy weather, so it is necessary to detour traffic Thursday night.

The detour will begin at 9 p.m. and end by 5 a.m. Friday. Traffic will not be detoured during regular daylight hours.

Southbound traffic will get off the interstate at Exit 13 and take Old Clyattville Road to Gil Harbin Industrial Boulevard, turn onto Madison Highway and return to the interstate at Exit 11.

Southern Concrete Construction Co. is removing a section of the bridge above lanes of traffic. The overpass was damaged in 2013 when a tractor-trailer crashed and caught fire under the west end of bridge. Repairs will include replacing portions of the deck and some of the beams and rehabilitating other parts of the bridge. The work will also affect Old Clyattville Road traffic.
